Regarding the ordering of songs, I don't think it is necessary. Naturally it will be better. Everyone will hear every song. Everyone comes to your wedding with blessings. You can choose a few favorite songs and put them in the opening.

The songs you choose are all very good. I'd like to recommend some songs to you, such as Dating by ChouHuei, Sweet Honey and Walking the Road of Life by Teresa Teng, Today and Love You for Ten Thousand Years by Andy Lau, Only You and Me on the Road to Love You Happiness by Richie Jen, Just Love You by Tao Zhe, I will by Faye Wong and I will by Yu Quan.

I think these songs are very suitable for the wedding atmosphere and have good meanings. I hope you will like them. I sincerely wish you a happy wedding and a safe and happy life.
